摘要：Disclosed is an apparatus comprising a first network node configured to transmit a first message to a second network node, wherein the first message comprises data designating the first network node as a member of a first multicast channel, and wherein the first message comprises data indicating a network address a third network node that is designated as a last hop router (LHR) of the first multicast channel. Also disclosed is a method comprising sending, by a first network node, a protocol independent multicast (PIM) join message, wherein the PIM join message comprises the network address of a PIM channel last hop router (LHR).

主权项：1. An apparatus comprising: a first network node configured to transmit a first message to a second network node, wherein the first message comprises data designating the first network node as a member of a first multicast channel, and wherein the first message comprises data indicating a network address of a third network node that is designated as a last hop router (LHR) of the first multicast channel, wherein the first network node comprises a table, and wherein the first network node is further configured to store the network address of the third network node and information indicating that the third network node is the LHR of the first multicast channel in the table.
